eKlima is a web site to access the database of climate data of the Norwegian Meteorological Institute from an external computer. The database contains measurements made by the Norwegian Meteorological Institute and its collaborators as far back in time as 1957. There are also some data that are older than that, with the longest data sets going as far back in time as 150 years. However, for the period before 1957 not all measurements are completely digitised yet.
